The Timing of the La Junta Tarantula Migration
When Does the Migration Occur?

The tarantula migration in La Junta typically takes place in the late summer and early fall, usually from late August through September, with the peak occurring in the middle of September.

What Triggers the Migration?
Several factors trigger the tarantula migration. The primary driver is the mating season, which is influenced by the seasonal changes. As the days become shorter and temperatures begin to cool, male tarantulas reach sexual maturity and begin their search for females. This instinctual drive to reproduce is amplified by environmental cues such as rainfall and humidity levels. The availability of potential mates in the area, along with suitable conditions for mating, further influences the timing and intensity of the migration. Understanding these triggers helps researchers and enthusiasts anticipate and appreciate the annual phenomenon.
